- the packaging material for the packaging container 1a is generally a flexible packaging material, such as a single-layer or multiple-layer plastic packaging material, a composite packaging material manufactured by laminating a plastic sheet with a metal foil, a metal-deposited film or paper, or a packaging material manufactured by coating or otherwise cladding a fabric web of natural or synthetic fiber with synthetic resin, at least the innermost layer of said packaging material being a heat-bondable.
- a flexible packaging material such as a single-layer or multiple-layer plastic packaging material, a composite packaging material manufactured by laminating a plastic sheet with a metal foil, a metal-deposited film or paper, or a packaging material manufactured by coating or otherwise cladding a fabric web of natural or synthetic fiber with synthetic resin, at least the innermost layer of said packaging material being a heat-bondable.
- said packaging container 1a there may be mentioned a variety of pouches, bottles, bags, bag-in-boxes, tubes, laminated tubes, milk cartons, composite cans, metal cans and so on.
- contents 1b which are filled into the packaging container 1a there may be mentioned various foodstuffs, pharmaceutical products, feedstuffs, and so on. Particularly important are foodstuffs.

- the packaging material 1a is filled with contents 1b to provide the package 1.
- the package 1 is irradiated with ultra-soft X-rays from outside in the above condition, whereby an image information is obtained.

- the fluorescence image and film image are usually obtained as life-size images, while the PbO-TV image as an enlarged image on a monitor screen.
- the occurrence or non-occurrence of degradation or the degree of degradation can be easily ascertained or evaluated, for when there is no degradation, the degree of dispersion of the head space is low, while when there is degradation the number of divided head spaces is greater with an increasing degree of degradation.
- the inspection apparatus comprises a shaking unit 2 for shaking the package 1 and a main inspecting unit 3.
- the main inspecting unit 3 is disposed downstream and independently of the shaking unit 2.
- the assembling of the shaking unit 2 with the main inspecting unit 3 as an integral setup should be avoided, for otherwise the vibrations of the shaking unit 2 are transmitted to the main inspecting unit 3 so that the X-ray beam from the ultra-soft X-ray irradiation device 32 goes out of focus on the vibrating package 1 to blur the image projected on the image display device 33.
- the shaking unit 2 comprises a first conveyer belt 21, a shaking machine 22, a retaining belt 23, and members ancillary to these element and devices.
- the first conveyer belt 21 is adapted to convey the package 1 in a downstream direction.
- the first conveyer belt 21 may be provided with dams 24 spanning the width thereof so that a row of packages 1 may be independently positioned between dams 24 and conveyed.
- the shaking device 22 is adapted to shake the package 1 traveling with the first conveyer belt 21.
- the shaking device 22 may be of any known construction, such as a device adapted to transform the rotary motion of a motor into a sinusoidally linear movement by means of a crankshaft and a rod, a device utilizing the attractive force of an electromagnet, a device employing a vibration motor (a motor having a drive shaft fitted with imbalance weights at both ends is driven to generate a centrifugal force), a device employing a mechanical vibrator or a device using an ultrasonic vibrator.
- the retaining belt 23 is adapted to support the traveling package 1 in cooperation with the first conveyer belt 21 and disposed in parallel with the first conveyer belt 21.
- the retaining belt 23 is preferably so designed that it is able to advance or retreat with respect to the first conveyer belt 21 and, upon contact with the package 1, is allowed to follow the movement of the package 1.
- the retaining belt 23 is preferably made of an elastic material.
- the main inspecting unit 3 mentioned hereinbefore comprises a second conveyer belt 31, an ultra-soft X-ray irradiation device 32, an image display device 33, and members ancillary to such element and devices.
- the second conveyer belt 31 is adapted to receive the package 1 from the first conveyer belt 21 of the shaking unit 2 and convey the package 1 further in a downstream direction.
- This second conveyer belt 31 need not be provided with partitioning means such as the dams mentioned hereinbefore.
- the width of the second conveyer belt 31 is generally equal to that of the first conveyer belt 21, although a minor difference is tolerated.
- the ultra-soft X-ray irradiation device 32 is adapted to irradiate the package 1 on the second conveyer belt 31 with ultra-soft X-rays.
- the term 'ultra-soft X-rays' as used herein means X-rays in the wavelength range close to ultraviolet rays, which are in contrast with the usual X-rays in the wavelength range close to gamma-rays.
- the ultra-soft X-rays are sometimes referred to simply as soft X-rays.
- the image display device 33 is preferably a system (a) comprising a fluorescent image-forming plate 33a, a fluorescent image photographing camera (CCTV) 33b and a television receiver 33c or a system (b) comprising a transmission soft X-ray photographing camera (PbO-TV) 33d and a television receiver 33c.
- the transmission X-ray image of the package 1 is formed as a fluorescent image on the fluorescent image-forming plate 33a and this X-ray image is photographed by CCTV 33b and projected on the CRT screen of the television receiver 33c.
- a sorting device 4 for discharging packages 1 found defective in isolation from packages 1 found acceptable.
- the package 1 In order to inspect a package 1, which is a packaging container 1a containing contents 1b, the package 1 is fed to the upstream end of the first conveyer belt 21 of the shaking unit 2 so that the package 1 may travel toward the downstream end of the belt 21.
- the shaken package 1 is then transferred from the first conveyer belt 21 of the shaking unit 2 to the second conveyer belt 31 of the main inspecting unit 3, by which it is conveyed in a downstream direction.
- the package 1 on the second conveyer belt 31 ceases to be vibrated at the upstream end of the second conveyer belt 31 and the head space dispersed into the contents 1b rises or coalesces owing to its buoyancy according to the viscosity of the contents 1b.
- the absorption of ultra-soft X-rays is greater with a substance of high density or thickness, and the long-wavelength soft X-rays show a pattern of transmission corresponding to the density distribution, yielding a well-contrasted sharp transmission image of good resolution.
- the contents 1b such as food
- the contents 1b are degraded or spoiled
- the inspector can render a judgement as to whether there is degradation or not or assess the degree of degradation and operate the sorting device 4 for culling out defective product packages.
